Line thickness in Makeitgood

All the lines connecting POS nodes, AI nodes etc are only a single pixel thick. I'm sure this was probably sufficient back in 1999 where screens were a quarter of the resolutions they are today and CRTs were relevant. But nowadays, a line that thin (especially on all kinds of different, brightly-colored backgrounds) is really hard to pick out.
It would be nice to have them be two or three pixels thick.
